Drying Kinetics Modeling of Bergamot (Citrus bergamia) Slices

Thin layer drying behaviour of bergamot (citrus bergamia) slice was experimentally investigated in a convective type dryer and the mathematical modeling assessed by using thin layer drying models given in literature. Drying experiments were conducted at inlet drying air temperatures of the 40, 50, 60, 70 and 80 °C; for samples of 6 mm thickness, at a drying air velocity of 2 m/s and with three replications in each treatment. Twelve different thin layer mathematical drying models were compared (according to their coefficients of correlation) to estimate the drying curves. The effects of drying air temperature on the model constants and coefficients were evaluated through a multiple regression technique. The models were compared according to three statistical parameters of: root mean square error, chi-square, and modeling efficiency. According to the obtained results, Midilli et al. model could satisfactorily describe the drying curve of bergamot (citrus bergamia) slices with EF=0.9992, x 2 =0.000259 and RMSE=0.013396 at different temperatures.
